.TransiEnt.Storage.Heat.HotWaterStorage_constProp_L4.Base.Buoyancy

Information

1. Purpose of model

Adds Buoyancy to a stratified storage.

2. Level of detail, physical effects considered, and physical insight

Convective energy flow is considered as heat flow of the same amount.

3. Limits of validity

Purely technical component without physical modeling.

4. Interfaces

heatPort[N_cv]: Gets the temperatures from the temperature layers and returns the heat flow due to boyancy back

5. Nomenclature

The input parameters

6. Governing Equations

(no equations)

7. Remarks for Usage

This model should be used to add buoyancy to a one dimensional water storage model.

8. Validation

9. References

This model is largely based on the model "Bouyancy" in the Modelica Buildings-library (https://github.com/lbl-srg/modelica-buildings.git)

10. Version History

Model revised by Pascal Dubucq (dubucq@tuhh.de) on Wed August 24 2016. Control volumes are now in intuitive order (1 = bottom, N_cv = top volume)
